THE EFFECT OF SPINAL POSTURAL ABNORMALITIES ON SPIROMETRIC INDICES

Postural abnormalities are one of affective agent on respiratory flow and Lung capacity. This study was carried out to investigate the effect of Postural abnormalities on spirometric indices in Hormozgan medical university. 60 volunteer students (23 males and 37 females) with age ranged 20-29 years oldfrom Hormozgan medical university through simple non-probability sampling were selected and their Lumbar Lordosis (from 12 thoracic vertebrae spinal process to 2 Sacral vertebrae spinal process) and thoracic kyphosis th nd (from 4 – 12 thoracic vertebrae spinal process) degrees measured via flexible ruler Model Mark Kidos. Subjects th Spiro metric indices such as (PEF, FEF , FEF , FEF , FEF , FVC, FEV ) measured via spirometer Model 25% 25%-50% 50% 75% 1 Spiro lab II. One way ANOVA and POSTHOC TUKEY test were used for statistical Analysis. Results showed that subjects with kyphosis abnormality have the lowest respiratory flow and Lung capacity and subjects with normal posture have the highest respiratory flow and Lung capacity. Spirometric indices such as PEF ‘FEV, FVC were statistically significant differences between kyphosis and lordosis abnormality groups 1 (p=0.001, p=0.001, p= 0.001 respectively), but there weren't significant differences between other indices (FEF (p= 0.212), FEF (p= 0.312), FEF (p= 0.311) , FEF ( p=0.124) respectively). Based on this study 25% 25-75 % 50 % 75 % results, we concluded that the spirometric indices changed with different Postural abnormalities.
